29 Claims.

The invention relates to printing machines for printing variable areassimultaneously.

The present invention differs from my former Patents 2,060,385 and2,085,126 by devising a I mechanism which will automatically print twodifferent designs'of. variable area simultaneously on the same article,whereas in the aforesaid patents, and in all other patents with which Iam familiar, only a singie design is applied to the 10 article at onetime. I accomplish this feature by providing a mechanism on the printingmachine which imparts a difierential rate of movement to the printingmembers which carry different areas in the design to be printed.

u Selecting, but not limiting myself to a bottle, for example, it hasbeen the custom to print a design on the body of the bottle, and then ina separate operation print a design on the neck of the bottle. Thedifliculty in printing on the body 20 and neck of the bottle resultsfrom the fact that the periphery of the body of the bottle rotates at agreater rate of speed than the periphery of the neck. The circumferenceof the body of the average beer bottle is approximately eight inches,

25 and the circumference of the neck is about four and one-half inches.This means that in order to simultaneously print on the body and neck ofthe bottle, the stencil or printing screen for the neck of the bottleshould travel only four and 30 one-half inches while the screen orstencil for printing thebody of the bottle travels eight inches. In mypresent invention, I print on the larger and smaller area of the samearticle, in

a very efllcient, satisfactory and economical.

35 manner.

Another feature of the present invention is to devise a mechanism whichperforms all these functions automatically.

A further object of the invention is to print bands, marks, designs,objects, letters, or numerals in series or otherwise, or combinations oftwo or more of the foregoing elements in color on the bodies and reducedportions of bodies, such as bottles, which may be made of materialspenetrable or impenetrable to the coloring materials.

With the foregoing and other objects in view, the invention consists ofa novel combination, assembly, construction and arrangement of parts 0as will be hereinafter more particularly described and illustrated inthe accompanying drawings, but it is to be understood that changes,variations, and modifications may be resorted to without departing fromthe invention in the claims.

Fig. 13 is a fragmentary perspective view of the chuck pin engaged inthe cam.

Referring to the drawings, it will be seen that the parts of the machineare mounted on a stationary support A composed of a pair of parallelinclinedside beams l6, 11 secured to a pair of legs l8 near the middle,and another pair of legs 19 at the lower end of the beams. On each sideof the support is a longitudinal brace '20 extending between thecorresponding legs I8, IQ of each pair of legs. Depending from the endsof side beams are a pair of transversely spaced brackets 22 in the endsof which are journalled a shaft 23 towhich is fixed the pair or idlesprocket wheels 24. About these sprocket wheels I are trained one end ofthe pair of transversely spaced endless chains 25 which form the upperor discharge conveyor on which the articles are dropped, or deposited,from the work carrying member B to be later described in detail. Theinner ends of the chains 25 are trained about driving sprockets 26 fixedon the drive shaft 21, which shaft turns the work carrying member B, andthe drive shaft is Journalled in bearings 23, one bearing being anchoredto each of the pair of supporting legs I 3.

The inner ends of a pair of outwardly extending arms 23 are secured tothe legs l3, andlin the outer free ends of the arms are Journalled thecharging conveyor drive shaft 30. On intermediate portions of shaft 30,are a pair of spaced sprocket wheels 3| about which are trainedrespectively, one of a pair of spaced endless chains 32 which form thecharging conveyor. On the pairs of conveyor chains 25 and 32 areV-shaped flexible prongs 33 fixed to the links. The members 33 on onechain of the pairs, align with the members 33 on the other chain to forma transverse pocket or saddle to receive the articles to be printed,which articles are shown in the drawings as bottles 34. Where articlesother than bottles are to be printed, the prongs may be of variousshapes to accommodate the shape of the article, and the space betweenthe chains of each pair may be regulated accordingly by adjusting therespective sprocket wheels for the respective pairs of chains by meansof the set screws 35, as is more clearly shown in Figure 6. It will beseen that the drive shaft 30 is drivenby a chain 36, one end of which istrained about the sprocket 31 on theend of the shaft, and the other endis trained about a sprocket 38 fixed on the outside of another sprocket39. The sprocket 39 idles on a spindle 40 secured at its inner end to.the outside of the support A on one of the longitudinal braces .20. ofthe charging conveyor is trained about a pair of spaced sprockets 4-lfixed to shaft 42 that is journalled in the legs l9.

On the one side brace 20 is anchored the prime mover, such as anelectric motor 43, the drive shaft 44 of which is connected to thetransmission gears mounted in gear casing 45, and extending from thegear casing is the drive shaft 46. One

sprocket wheel 41 fixed to the drive shaft 46 on the inside, drives thesprocket 41 on the outer end of the crank shaft 48 by means of chain 49.Another sprocket wheel 50 on the outside, and fixed to the shaft 46,drives the work carrying member B by an endless chain trained about theGeneva gear C on the outer end of shaft 21. The chain 5| passes over thespring pressed sprocket 52, and about idler sprocket 39 from whichsprocket 39, on the lower or charging conveyor receives its drivingpower as heretofore described.

The crank shaft 48 is journalled in the ends of the side beams |6--l'l,and in the centeris made with a bifurcated crank 53 between the arms ofwhich the bearing collar 54 on the outer end of connecting rod 55 isjournalled on the bolt 56 secured to the crank arms 53. The bolt 56 isslidable in slots in the arms 53 to adjust the throw of rod 55. On theterminal of crank shaft 48, outside of sprocket 41, is fixed a secondcrank arm 51 having a slot 53 which accommodates the adjustment of abolt or crank pin 59 on which is mounted a ring bearing 60 on theconnecting rod 6|. As will presently appear, the difference in throw incranks 53 and 51, with other ex- The other end of the chains 32 twoprinting members D and E, with which are associated respectively ascraping member F and G. As will presently appear, the printing membersvibrate or oscillate in a normally rectilinear path and the scrapingmembers sweep coloring material over the printing surface on both theoutward and return stroke of each vibration or oscillation. The coloringmaterial passes through the parts of the printing surface that arepervious to the coloring material and the coloring material passingthrough the pervious parts is transferred to the articles brought intocontact or coincidence with the path of the oscillating printing surfaceby the work carrying member B. It will also be clear, as the descriptionproceeds, that suitable mechanism is provided to move the printingmembers D and E toward and away from the normal vibratory or oscillatorypath at the end of the stroke in one direction, and at the end of thereturn or backward stroke. The scraping members F and G are likewisemoved toward andaway from the path of the printing members at the timethe printing members are moved out of their normal path. The movement ofthe printing members and the scraping members out of their normalpath ofoscillation prevents smearing the printing after it has been transferredto the articles.

The main printing member D is arranged to move over the body, and theauxiliary printing member E is arranged to move over the neck of thebottle 34, carried in the work carrying member B. The main printingmember D includes a carriage made up of two rectangularframes disposedone above the other, the upper one of which is indicated at 62 and thelower one being indicated at'63. Both frames normally vibrate oroscillate simultaneously and continuously in a rectilinear path, but theupper frame that carries the main printing box to be presentlydescribed, moves toward and away from the normal path of oscillation atthe end of the stroke in one direction, and also at the end of thereturn stroke in the opposite direction. The end rail 63a of lower frame63 has a pair of bearing ears 64. Between the ears on the pin 65,secured in the ears, the sleeve bearing 66 on the inner end ofconnecting rod 55 is journalled. Crank shaft 48 imparts the vibratory oroscillatory movement to the main printing member D through theconnecting rod 55 and the frames 63 and 62.

The side rails 63b of the lower frame 63 have laterally projecting ribs61 which slide in channels 68 on the side beams l6, I! of the support Aand this provides for the oscillatory movement of main printing memberD. The upper frame 62 of the carriage is supported on the lower frame 63by means of four upright trip pins 69 located near' the comer of theframes. The heads of these pins 69 are fixed, as by riveting, to theside rails 62a of frame 62. The shanks of these pins 69 slide inopenings in the side rails 63b. A trip rod H is slidable in alongitudinal bore 72, one in each side rail 63b, and the trip rod has aV-shaped cam notch 13 cut therein, one for each pin. The inner end ofthe pins 69 normally rest in the lowermost part, or trough of the camnotches 13.

The outer ends of the trip rods ll extend free of the ends of the lowerframe and on each projecting end there is a spring 14, one end of whichbears on the frame 63, while the other end of the spring bears againstnuts 15 threaded on the terminals of the trip rods. Brackets I6, one ateach end of each of the trip rods 1|, are bolted to the side beams I8,ll of support A, and in each bracket is an adjustable abutment, eachofwhich consists of aheaded bolt", the threaded shank of which extendsthrough openings in the bracket. The heads on the bolts are in alignmentwith ends of trip rods II. The threaded shanks of bolts I! carry nuts I8one on each side of the bracket; 'By tightening the nuts, the bolt isheld fast, and when they are loose the bolt may be adjustedlongitudinally of the bracket.

The springs I4 normally support the trip rod H in the position where theinner end of cam pins 69 rest in cam notches 13. When the trip rods 'IIstrike the abutments embodied in the bolts 11, at either end of thestroke of the printing members, the springs I4 at the end where thestriking occurs, as shown in Fig. 1, are compressed as the trip rodmoves. Whenthe trip rod moves, the cam pins 69 raise out of the camnotches 1 3, and the upper frame 62 movesat right angles to the normalpath of oscillation. Since it will appear later that both printingmembers D and E move with the upper frame 62, then they are likewisemoved into and out of their normal oscillatory paths by the samemovement.

The rectangular printing box of the main printing member D is composedof side andend rails I9, 88 respectively, which form upstanding sides tothe box for the purpose of confining the coloring material within thebox. The printing box for the main printing member D is adjustable inthree directions, that is, longitudinally and transversely of themachine, and also up and down. To accomplish this function, a pair ofright angled arms at each end of the printing box have the legs 8Islotted at 82 to receive the shanks of bolts 83 which slide in the slots84 in the end rails 62b of the upper frame 62. The upright legs 85 ofthe arms are slotted at 86 to receive the shank of bolts 81 anchored tothe end rails 88. By loosening the wing nuts on the respective bolts 83and 87, the main printing box may be adjusted, and by tightening thenuts, the boxes are secured in adjusted position on the upper frame 62.

The auxiliary printing member E includes a separate and distinctcarriage member, shown particularly in Fig. 7, which imparts adifferential oscillating movement to the auxiliary printing member withrespect to the main printing member D. The carriage is composed of apair of bearing blocks 88 slidable in a guide slot 89 in the one sidebeam I! of support A. Secured to and extending from the outer one ofblocks 86 is a pin 98 connected to the inner end of connecting rod 6 Ifrom which the auxiliary printing member E obtains its normal continuousand oscillating motion in a rectilinear path. From the inside one of thepair of blocks 88 projects a lug 9I, fixed thereto in any suitablemanner. A second connecting rod 92 is connected at its outer end to thislug 9i by nut 93 threaded on the rod and bearing, one on each side,against the lug. The inner end-of connecting rod 92 is connected as at94 to the confronting end of the bearing block 95 which slides in aguide channel 96 on the adjacent side rail 63b of the lower frame 63 ofthe carriage for the main printing member D. Connecting rod 92 extendsthrough a slot 91 in end rail 63a of frame 63. It will thus be seen thatthe carriage for the .respective printing boxes.

panels H8 are the same in both the main and auxiliary printing member Emay normally oscillate independently of, and at a differential rate ofspeed from the main printing member D so that a smaller printed area maybe printed on the neck of a bottle at the sametime a larger area isbeing printed on the body of the bottle.

It is necessary to provide a structure capable of moving the auxiliaryprinting member E toward and away from its normal path of oscillation sothat the printed matter will not smear, and also to provide for printingon both the outward and return stroke.v To do this, I mount a U-shapedmember sidewise to slide on a pair of upright pins 98-that extendthrough the legs 99 of the member and across the outwardly openingchannel I88 thereof. There are heads IN on the lower ends of the pins 98which bear against the bottom face of one leg 99 and support the member.A portion of bearing block 95 extends into the channel I88 of themember, and on this portion the shanks of the pins 98 slide up and down.There are springs I82 under the portion of the bearing block 95 thatextend into thechannel, encircling the pins 99, and bearing against thelower leg 99 so as to normally urge the U-shaped member downwardly. Theupper end of pins 98 extend through a. guide slot I83 in a bar I84 topermit longitudinal movement of the pins. The ends of bar. I84 are fixedto the end rails 62b of the upper frame 62 and extend across the upperframe. There are nuts or bearing heads I85 threaded on the upper ends ofthe pins 98 which slide onthe upper face of the bar I84. Between thelower face of the bar I84, and the upper leg 99 of the U-shaped member,there are springs I86 embracing the pins 98, which hold the U-shapedmember down on the projecting portion of bearing block 95, but'when theupper frame 82 is raised, as heretofore described, the bar I84; raisesand moves the auxiliary printing member E with it.

, The printing box of the auxiliary printing member E is rectangular inshape and smaller than the printing box for the main printing member D.The auxiliaryprinting box has upstanding side and end rails I81, I88respectively to confine the coloring material within the box.

The printing box for the auxiliary printing member E is'adjustabletransversely and longitudinally, and is also adjustable up and down onangle brackets, one at each end rail I88. One leg I89 of each bracket isslotted at II8 to receive a shank of a bolt I I I anchored in the centerof each end rail I88. Nuts on thebolts III secure the box to the legI89. The upright leg II2 of the brackets is slotted at H3 to receive theshank of a bolt II4 having a head II5 on the inner end thereof slidablein a channel II6 on the web II'I of the U-shaped member. Wing nuts onbolts II4 hold the brackets to the U-shaped member.

The printing surface'for the printing boxes for the main printing memberD and the auxiliary printing member E consists of a panel II8 one foreach printing box, and this panel is secured to the lower edges of theside and end rails of the Except for size, the

auxiliary printing members D and E. The panels II8 may be made of acustomary. metal stencil or a regulation cloth or silk screen. Thepanels form the surface to support a gob of coloring material whichforms the design printed on the article 34 and they are impervious tothe coloring material, except for the part II9 carrying the design, andthis part II9 is pervious to the when it is brought into coincidencewith the path of oscillation of the printing members by the workcarryingmember B. The coloring material may be in powder, liquid, or plasticform customarily used in this character of printing.

In printing with my machine, the coloring material is swept back andforth over the panels iIB-by the scraping members, F indicating thescraping member for the main printing member D, and G indicating thescraping member for the auxiliary printing member E. As the scrapingmembers sweep the coloring material back and fortli'over the panels,-apart of it passes through the pervious parts H9 and is transferred tothe article, or bottle 34 on the work carrying member B.

Each of the scraping members F and G consists of a rigid metal or woodenshoe having a shank I20 provided with slots I2I. On the lower end of theshoes are flexible squeegee blades I22, preferably made of rubber, whichare in wiping engagement with the panels I I8, and these blades scrapeand sweep the gob of coloring material over the panels. The shoes ofeach scraping blade have their shanks I20 adjustably connected to across head I23, which extends across the machine. The cross head has aslot I24 extending through its thickness, and also extending across themajor portion of its length, and bolts I25 in loose condition areslidable in these slots. The shanks of the bolts I25 passthrough theslots I2I in the shanks I20 of the shoes, and have wing nuts on theirends whereby the bolts may be tightened to hold the shoes in fixedrelation to the cross head I23 for the scraping members F and G in anydesired adjusted position. It will be seen that-the adjustmentis'transversely of the machine, and also up and down.

It is necessary to provide mechanism to make the scraping members stepfrom one side to the other of the gob of coloring material at the end ofthe outward stroke and also at the end of the inward or return stroke ofthe printing members so that printing may be done in both directions ofthe oscillating path like in my copending application Ser. No. 204,653,filed April 27, 1938. Toward this end, I provide sleeves I26 at each endof the cross head which slide up and down on the posts I21, there beingone post the upper face, near each end of the side rails are pairs ofcams I30, I30a respectively, th'e'pair at one end being staggered withrespect to the "pair atthe other end. Adjacent the ends of the crosshead are pairs oi fingers I3I, I3Ia mounted side by side in brackets I32fastened to the cross head and these fingers rock in one direction, butare rigid to movement in the opposite direction. With the parts in theposition shown in Fig. 1, fingers I3Ia have raised the cross head overcams I 30a, and will swing loosely in the bracket on the return stroke,at the end of which, fingers I3I are rigid when they contact cams I30,and swing freely on the return stroke. This movement causes the bladesI22 to step from one side and come to rest on the other side of the gobof coloring material ready to sweep the coloring material in theopposite direction when the printing members D and E make the returnstroke in their oscillatory path. v

The work carrying member 0 includes a. pair of disks I33 mountedconcentrically on the shaft 21 in axial spaced relation, The disks turnsimultaneously with the shaft 21. The one disk I33, at the left, asshown in Fig. 6 is adjustable to accommodate different lengths inbottles.

The hub- I330, has a channel that supports half of a key I33c whichslides in a keyway I33d. Keyway I33d extends throughout three-quartersof the length of shaft 21 and a set screw I33b on the hub I33a bearingon the key I33c locks the said one disk in any desired adjustedposition.

I have found it desirable to provide four article work holding stations,although any number may be used. With this in view, I provide fourcircular chucks I34 on one disk and four circular chucks I35 on theother disk corresponding in position to the chucks I34. Chucks I34 gripthe base of the ,bottle 34, and chucks I35 grip the neck about the mouththereof with the bottle axis disposed transversely across the machine.The periphery of the chucks I34 contact a flexible strip I36 to bepresently described, to impart a rolling motion to the bottle or articleheld by the chucks, equal to the rate of movement of the printing memberD only. That is, if the printing member D moves 12 inches in threeseconds, the circumference of the body of the bottle 34 will move anequal distance during the same time. Chucks I34 are free to rotate onthe pins I31 anchored in the adjacent disk I33. The chucks I34 have acavity I38 in inner face to receive the bottom of the article such as abottle 34, and the chucks I35 have a corresponding cavity to fit themouth of the bottle. The face of the chucks may be shaped about theperiphery of these cavities to correct any error in timing the pick-upof the bottle, and also to center the bottle.

Chucks I35 are capable of axial movement which allows them to grip andrelease the neck end'of the bottle 34 automatically. With this in mind,I fix one end of the pins I39 to the chucks. The shanks of the pins I39slide and rotate in openings in the corresponding disk I33 and projecton the outside where a fiat head I40 is formed. Between the disk I33 andthe confronting face of the chucks I35 are coil springs I, one embracingeach of the four pins for the four chucks. One end of the spring bearsagainst the disk and the other end against the corresponding chuck.Chucks I35 are normally urged inwardly by the action of the spring, butwhen the object or article is gripped, the heads I40 project outwardlyof the outer face of the corresponding disk.

On the inside of the support A is anchored a semi-circular cam race I42of channel-shape in cross section which has the inclination of such apitch that the pins I39 are pulled outwardly in the position X in Fig.12 of the draw- .ings sufliciently to release the bottle 34, at whichposition the bottle is deposited on the cradle made by. prongs on thedischarge conveyor made up of chains 25. The'head I40 remains ,in theextended position during the rotation for another quadrant, and at theposition indicated at Y in Fig. 12 of the drawings, the head I40 slipsfree of the cam I42. At the point Y, a bottle 34 on-the chargingconveyor made up of chains 32, is in substantial alignment with thecorresponding chucks I34 and I35, and when the chuck I35 snaps inwardlyunder the tension of spring I4I, the bottle is gripped between thechucks. From the Y position in Fig. 12, the bottle is moved to theprinting position Z shown in Fig. 12 of the drawings, and the relationof the bottle 34, the one printing member D, the corresponding scrapingmember F, and the work carrying member B in the position correspondingto the position Z, is shown In Fig. 11 of the drawings.

The work carrying member B is timed to rotate a quadrant of a revolutionwhile the printing members D and E are raised by the trip rod H at eachend of their oscillating path. This movement also occurs while thescraping members F and G are raised. Thus one bottle 94, is moved intothe path of the oscillating printing surface, while the bottlepreviously printed is moved away from'the path and released on thedischarge conveyor 25. This timed movement is controlled by the Genevagear similar to that shown in my aforesaid co-pending-application.

This Geneva gear comprises an inner disk I55 keyed or otherwise fixed toshaft 21, and fixed to the hub H56 of the inner disk by means of boltsI51 is the outer disk I56. Between the two disks is a third disk I59which is free to rotate on shaft 21. The chain 5I bears on the peripheryof disk Q59 and the disk is rotated continuously by the chain.

Spaced equidistantly on the chain 5! in predetermined positions are anumber of lugs or cams I60, which are designed to engage and swing alocking pawl I6I pivoted to leg I8 of support A at I62. The a bill orextension I63 that engages a notch I64 in the flange of the inner diskI55. A number of these notches I64 are provided and they are spacedequidistantly around the flange of disk I55 to correspond with thenumber and position of the chucks I34-I35. On the side of pawl I6I isfixed a pin on which the roller I65 is mounted. The pawl I6I is normallyheld seated in one of the notches I64 on disk I55 by a spring I66anchored at I61 to the leg I8 at one end and to a projection I58 on thepawl at the other end. As the chain' 5I travels over the idler disk I69the pawl is engaged in one notch I64, and the shaft 21 is locked againstmovement. I

Extending outwardly and fixed to the chain 5I are a number of pins I69spaced equidistantly on the chains so as not to interfere with themovement of the chainover the other sprockets about which the chaintravels. Formed on the periphe y of each of the inner and outer disksI55. I58 respectively, are pairs of aligned cleats I10 which are spacedequidistantly about the disks and each cleat is fashioned with astraight trailing face H011 and a round leading face I101). The cleatsI10 correspond in number and position with the chucks l94l35.

The pins I69 engage the straight faces of the corresponding pair ofcleats I10, at the same time the cam I60 raises the locking pawl I6I andthe shaft 21 is turned about a quadrant of a revolution. This positionis shown in Fig. 8 of the drawings. When pawl I6I drops free of the camI60, it rides on the flange of inner disk I55 until it drops into thesucceeding notch I64 whereupon ,of the cleats no with which free end ofpawl I6I has the disks are locked and the shaft 21 together with workcarrying member Bis made stationary while the printing members 1) and Eimmediately thereafter begin another stroke. At about the same time thepawl I6I locks the disks I55I58,

the pins I69 will have traveled a quadrant of a circle around the disksand are ready to drop free they have been engaged. To provide a certainamount of pressure to cause a whip or backlash in chain H to insure thepins I69 will jump free of their engaged cleats in case the pawlmomentarily locks before the pins I69 are free, .an arrangement is madeto provide tension against the roller 52.

An intermediate part of plunger I1I slides in a sleeve bearing I12, andthe bearing has ears I13 fastened to leg I8 by bolts I14. The outer endof the plunger extends outwardly of the bearing and is threaded toreceive a nut I15. On the inner end of the plunger is a bearing for thespindle I16 on which the sprocket wheel 52 rotates. Between the spindlebearing and the inner end of the bearing I12 is a spring I11 whichapplies tension on thesprocket wheel 52, which tension may be regulatedby screwing the nut I in or out on the end of the plunger I1I.

It will be seen that I obtain compound movement in the work carryingmember B. The one component is the intermittent rotary motion obtainedby the Geneva gear C, which moves the articles into and away fromprinting position in the vibratory or oscillatory path of the printingmembers D and E. The other component is the rolling motion produced whenthe periphery of that chuck which is in printing position, engages thefriction strip I36 causing the article to rotate at the same rate ofspeed as the main printing member-D.

The endless chain 5I is rotated continuously by the sprocket 50, and thechain passes over Geneva gear C, the tension sprocket 52, and thesprocket 39. When neither of the pins I69 nor the cam I60 are engaged,the chain 5I travels about the center disk I59 which idles on the shaft21. While this phase of operation is occurring, the printing members Dand E are performing the printing operation. At the same time, pawi I6Iis engaged in one of the notches I64 in the'disk I55, and the disks I33are stationary, while the one chuck I34 that is in printing position isbeing turned by engagement with the friction strip I36 at the same rateof speed at which the printing panel I I8 on the main printing frame Dis wiping over the body of the bottle that is in printing position. Atthe same time the panel III! on the auxiliary printing member E iswiping over the neck of the same bottle, at a slower rate of speed thanthe panel II8 on the main printing member D, since there is a smallerarea to print on the neck than there is on the body. The differentialmovement between the main and auxiliary printing members is produced bythe difference in throw of the cranks 53 and 51 respectively, and

printed; then the one pair of pins I69 on chain 5I engages thecorresponding pair of cleats I10 15 on the disks I55 and I53, and thecorresponding cam I60 lifts the pawl I6I, all of which results insimultaneous release of shaft 21 and the turning thereof for about aquarter of a revolution. The turning of the shaft 9. quarter turn movesone bottle away from the printing position and places the succeedingbottle in printing position while the printing members and scrapingmembers are in the raised position.

During the time interval the pins I59 have traveled over a quadrant ofthe disks I55I58 I59 that form the Geneva gear C, the printing membersshallhave been raised from their'printing position. At the moment thepins I59 free themselves from the cleats I19, the pawl I5I drops intothe succeeding notch I84 in disk I55, and this action locks the workcarrying member B with the one bottle I34 in printing position. At thesame time, both printing members D and E and the scraping members F andG .drop or return from their raised positions to their normal positionsand continue on the printing stroke in the opposite direction ready togo through the sequence of steps just described at the end of thestroke.

It is necessary to adjust strip I36 to accommodate the adjustment of theone chuck I33 transversely of the machine. The strip I36 is fixed to thelower edge of a wooden plate I44 and the plate is secured to a block I45by a pair of spaced bolts I46, the heads of which are anchored in theblock. The threaded ends of the bolts exand have knurled nuts I52 on theprojecting ends. The bar I 5| has a clamping Jaw I53 which extendslaterally of the bar and seats in a groove I54 in side rail 63b of thelower frame 53. The lower bar is likewise formed with a clamping jawI49a which seats in a groove corresponding with groove I54. It will thusbe seen that by loosening nuts I52 the bars I5I and I49 together withblock I may be moved transversely of the machine in any desired positionwithin the limits of the width of the clampingjaws I53 and Him.

Across one end of support A, there is secured to the end legs I9, asheet metal skirt I99 as a protection to the operator from the throw ofcrank 53.
